Analysis and Comparison of Vitamin C Levels in Srikaya Fruit (Annona Squamosa L.) and Soursop Fruit (Annona Muricata L.)

Introduction

Vitamin C is one of the most essential vitamins for our health, often associated with increased endurance. As an antioxidant, this vitamin is effective in fighting free radicals that can damage the body's cells. Among the other types of vitamins, vitamin C is probably the best known and widely sought in society. Fresh fruits, including srikaya and soursop, are natural sources that are rich in vitamin C. This study aims to compare the content of vitamin C in srikaya and soursop fruit that is common.

The Importance of Vitamin C in Our Diet

Vitamin C is a vital nutrient that plays a crucial role in maintaining our overall health. It is essential for the production of collagen, a protein that gives structure to our skin, bones, and connective tissue. Vitamin C also helps to boost our immune system, fighting off infections and diseases. Furthermore, it acts as an antioxidant, protecting our cells from damage caused by free radicals. With its numerous health benefits, it is no wonder that vitamin C is one of the most sought-after vitamins in society.

Research Methodology

The study begins with sampling of srikaya and soursop fruit from the market. After that, the sample obtained through the processing stage to prepare for the analysis. In this process, the need for reagent solution and the required pentiter solution. Then, the level of vitamin C in processed fruit samples is determined by the titration method using a 2,6-dichlorophenol indofenol solution.

Research Result

The analysis showed that the level of vitamin C in srikaya fruit was 67.32 ± 1.46 mg/100g, while in soursop fruit, the vitamin C levels reached 42.16 ± 1.73 mg/100g. This shows that srikaya fruit has a higher vitamin C content compared to soursop fruit. Recovery tests conducted showed a percent recovery of 93.8197%, with a RSD value of 1.1858%. This shows that the method used in this study is quite accurate and reliable.

Analysis and Discussion

A significant difference in vitamin C levels between srikaya and soursop fruit can be caused by various factors, including varieties, cultivation, and environmental conditions where the fruit grows. Srikaya fruit, with a soft texture and sweet taste, may have a different metabolic process in vitamin C synthesis compared to soursop fruit which has a sour taste.

In addition, storage and processing methods can also affect vitamin C levels in fruit. Vitamin C is a vitamin that is soluble in water and is very sensitive to heat, so the incorrect cooking or processing process can cause losses of this vitamin level. Thus, it is important to consume it in fresh form to get maximum benefits.

The high vitamin C content in srikaya fruit makes it an excellent choice as a source of nutrition, especially for those who want to increase endurance. Meanwhile, although soursop has lower levels of vitamin C, it still has other health benefits, including antioxidant content that is beneficial for overall health.

Comparison of Vitamin C Levels in Srikaya and Soursop Fruit

Fruit	Vitamin C Level (mg/100g)
Srikaya	67.32 ± 1.46
Soursop	42.16 ± 1.73

As shown in the table above, srikaya fruit has a significantly higher level of vitamin C compared to soursop fruit. This suggests that srikaya fruit is a better choice for those who want to increase their vitamin C intake.

Conclusion

From the results of the study, it can be concluded that there are significant differences in vitamin C levels between srikaya and soursop fruit. Srikaya fruit has a higher level of vitamin C, so it can be a better choice to meet the daily needs of vitamin C. However, both of them still provide health benefits. Given the importance of vitamin C for the body, consumption of fresh fruits should be increased as part of a healthy diet.

Recommendations

Based on the findings of this study, the following recommendations can be made:

Srikaya fruit can be considered as a good source of vitamin C, especially for those who want to increase their endurance.
Soursop fruit, although having lower levels of vitamin C, still has other health benefits, including antioxidant content that is beneficial for overall health.
Fresh fruits should be consumed regularly as part of a healthy diet to meet the daily needs of vitamin C.
Storage and processing methods should be improved to minimize losses of vitamin C in fruit.

Limitations of the Study

This study has several limitations, including:

The study only compared the vitamin C levels in srikaya and soursop fruit, and did not investigate other types of fruits.
The study only used a titration method to determine the vitamin C levels, and did not use other methods, such as high-performance liquid chromatography (HPLC).
The study only analyzed the vitamin C levels in fresh fruits, and did not investigate the effects of cooking or processing on vitamin C levels.

Future Directions

Future studies can build on the findings of this study by:

Investigating the vitamin C levels in other types of fruits.
Using other methods, such as HPLC, to determine the vitamin C levels.
Analyzing the effects of cooking or processing on vitamin C levels.
Investigating the health benefits of consuming srikaya and soursop fruit.
